The four apartment-concept developed around the Mobius strip concept was originally supposed to be built in Murska Sobota, Slovenia; made of a reinforced light-transmitting concrete(Litracon), the building will take advantage of this technology to absorb filtered light throughout its entire outer shell.
The Möbius strip or Möbius band is a surface with only one side and only one boundary component. The Möbius strip has the mathematical property of being non-orientable. It is also a ruled surface. It was discovered independently by the German mathematicians August Ferdinand Möbius and Johann Benedict Listing in 1858.

A model can easily be created by taking a paper strip and giving it a half-twist, and then joining the ends of the strip together to form a loop. In Euclidean space there are in fact two types of Möbius strips depending on the direction of the half-twist: clockwise and counterclockwise. The Möbius strip is therefore chiral, which is to say that it has "handedness" (as in right-handed or left-handed).

This single continuous curve demonstrates that the Möbius strip has only one boundary.
